Osmosis and Water Potential Year 11 Emary Venter INTRODUCTION: The cell is the basic unit of living things‚ and is made up of multiple organelles. Organelles are membrane bound subdivisions‚ each specialised for a specific function. This experiment looks at the Plasma Membrane‚ which is a semipermeable layer surrounding the cell. It’s primary job is to control what goes in and out of the cell. Molecules can move across this membrane in either an active movement or a passive movement

Diffusion and Osmosis Experiment Methods/Materials: 7.1 Experiment: Rate of Diffusion of Solutes In the initial set up of this experiment I had 2 sets of 3 screw-cap test tubes that had each been half-filled with 5% gelatin and 1-mL of the correct dye (either potassium dichromate‚ aniline blue‚ or Janus green) in each of the test tubes. I labeled the 3 test tubes of set 1 with which die they contained and marked them “5 ˚C”. Then with the other set I did the same exact thing‚ except I labeled

concentration of the reactants and products does not change with time. Before this experiment‚ we were educated on how osmosis functions. Osmosis is a process which molecules and water take to usually get through a selectively permeable membrane in order to reach equilibrium. It is a passive transport which requires no ATF and water moves from high to low water concentration. When osmosis is completed‚ there should be an equal concentration o water on both sides of the experiment. We have also learned

eating all those sugars? We’ve said it before‚ and we’ll say it again: We consume a lot more sugar than is good for our health. Because of this‚ the next generation of Americans will struggle with obesity and diabetes more than any other. The most obvious culprit is the added sugar in sodas and other sugary beverages‚ like sports drinks or teas. One idea public health advocates have floated to bring sugar consumption down is to tax beverages with more than a certain amount of added sugar. (Berkeley‚ Calif

our overconsumption of sugar has led to diabetes. Chances are extremely high that you know someone with type 2 diabetes. The Centers for Disease Control and Prevention said that the incidence rate for diabetes type 2 was at least 50% in most states between 1995 and 2010 and some states saw an increase of 100%. States in the southern part of the United States saw an increase in diabetes diagnosis of 226% (Oklahoma) and the incidence rate for obesity was just as high (“Sugar and Desserts: American

Sugar was not only a stimulant to consumers but also for anyone else in the production of it‚ more and more sugar was being demanded‚ perhaps because of it accessibility or the money that came out of it. If it weren’t for producers‚ consumers‚ and entrepreneurs sugar production would not have been one of the biggest productions of a crop in the world. The organization of sugar met the needs of producers‚ because sugar production was profitable and did not consist of many owners; it met the needs

Sugar subsidy is a very sensitive issue among Malaysian nowadays. Some believe that the sugar subsidy give a lot of benefit to them. Since‚ they are enjoying the cheaper price of sugar without thinking about the consequences especially their health. Therefore‚ government should cut sugar subsidy to promote healthy living‚ to curb wastage‚ and to develop our country. Our government should end sugar subsidy to promote healthy living to all Malaysian. According to Datuk Tan Lien Hoe‚ the Domestic

What drove the sugar trade? Theodore Roosevelt once said‚ “Do what you can with what you have‚ where you are.” For the British this meant using islands such as Jamaica and Barbados to produce‚ process‚ and sell sugar. Sugar cane thrives in hot humid‚ tropical climates. The British used sugar for things such as rum‚ molasses‚ and other auxiliaries. The sugar trade grew and thrived for three specific reasons: the perfect climate was available; sugar was new to Britain so people wanted

germination is the uptake of water by the seed. This is the part where osmosis takes place. Osmosis is the diffusion of water across a selectively permeable membrane in which the water moves from a high concentration to an area where there are water molecules with a low concentration. Osmosis is similar to diffusion in the way mentioned earlier with the molecules moving from high to low concentration. Another similarity that osmosis shares with diffusion is that both processes work as passive transports
